Remark

1.       All parameters are specified at 230VAC input, rated load2570% RH ambient;

2.       Ripple & noise are measured at 20MHz by using a12’’ twisted pair terminated with a  0.1uF &47uF capacitor;

3.       Tolerance: includes set up tolerance, line regulation and load  regulation;

4.       Line regulation is measured from low line to high line from the rated  load;

5.       The over temperature protection is the built in function of the control  IC.

Q: Why is efficiency important?

 

A: Quite simply, if your power supply is more efficient, your devices will use less power.  Depending on how much you pay for power from your utility company and how much power your devices typically use, you can save money.

 

Furthermore, because any AC power that is NOT converted into DC power is exhausted as heat, a more efficient power supply inherently runs cooler.  Not only does this mean your office is going to be cooler, but also allows BFG to use a slower, quieter fan to cool the power supply.

 

Q: What is power factor correction?

 

A: Poor power factor can be corrected by adding some form of power factor correction to the AC input of the power supply. Power Factor Correction comes in two forms: Active Power Factor Correction, or APFC, and Passive Power Factor Correction.

 

Passive Power Factor Correction uses a filter that kills any harmonic current and passes current only at line frequency (typically 60Hz in theU.S.) The filters typically come in the form of large, high-value inductors.

 

Active Power Factor Correction is done by using a boost converter in between the bridge-rectifier and main input capacitors. The boost converter attempts to maintain a constant output voltage while drawing a current that is always in phase and at the same frequency as the line voltage.
